Utilisation of diesel engine waste heat for ship's ballast water heat treatment

Heat has been proved to be a very attractive method of minimizing the risk of introducing new organisms into the ports where ballast is discharged. It does not necessitate the use of chemicals or biocides that could be harmful to the environment. Waste heat from a ship's main engine can potentially provide a cost-effective source of heat. An analysis of available heat and methods to obtain required ballast water temperature with maximum efficiency is the main concern of this paper. To obtain required ballast water temperature without affecting engine performance and fuel consumption appropriate modifications of ballast piping and diesel engine conventional and central cooling systems have been proposed.
